SPEGIFIGATION forming part Of Letters Patent No. 678,762, dated July 16,1901.

A lication fil d, April 8, 1901. Serial No. 54,962. (No model.)

To all? whom it may concern:

Be it known that I, JAMES E.- POTTER, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements inCollar-Buttons, of which the following is a specification, referencebeing had therein to the accompanyin g drawings.

Like letters indicate like parts.

Figure 1 is a top plan of a pointer collarbutton. Fig. 2 is a section ofmy invention as seen on line mm of Fig. 1, the end of shank of therivetbeing shown before the same has been spread. Fig. 3 is an invertedplan view. Fig. 4 is a plan view of the inner plate or disk of thebutton-head. Fig. 5 is an end edge view of the same. Fig. 6 is a topplanof the rivet. Fig. '7 is a front elevation of said rivet. Fig. 8 is aside elevation of the same. Fig. 9 is a perspective view of saidpointer-button. Fig. 10 is a central longitudinal section of saidbutton, the end of the rivet-shank being shown after the same has beenswaged into contact with the inner surfaces of the hollow shank of thecollar-button. Fig. 11 is a sectional View as seen on line 1 y of Fig10. Fig. 12 is a plan view of a modified form of the lining-plate of thebutton-head. Fig. 13 is a sectional view of the same as seen on line a zof Fig. 12. Fig. 14 is a sectional view as seen on line to w of Fig. 12.Fig. 15 is a view of my improved device as applied to a leverpointer-button, said view being partly in central longitudinal sectionand partly in elevation. Fig. 16 is a central longitudinal section ofthe same as seen on liner: 1; of Fig. 15. Fig. 17 is a perspective viewof the rivet modified to adapt it for use in lever-buttons. Fig. 18 is acentral longitudinal section of the button shank and shoe with the rivetin position therein shown in elevation. Fig. 19 is a centrallongitudinal section as seen on line to u of Fig. 18, the rivet being,however, shown in 45 side elevation. Fig. 20 is a detail view showingthe modified form of the lining-plate, which is separately illustratedin Figs. 12, 13, and 14., in position and relation to the contiguousportions of the collar-button.

My invention relates to collar-buttons, and

more especially to the means of securing the heads thereof to theshanks; and it consists of the novel construction and combination of athe several parts, as hereinafter particularly described and asspecifically set forth in the claims.

The principal novelty in this invention is the use of an inclosedconcealed rivet which unites the head and shank of the button and sodispenses with the use of solder for that purpose.

In the drawings, A represents the outer shell or rolled covering-plateof the head of a pointer collar-button,'l3 the shank, and (J the shoe.The parts B and O are integral, as shown. The shank B, as appears inFig. 9, is rectangular in cross-section and Wider from side to side thanfrom front to rear.

D is an inner plate or disk within the head of the button.

E is the circular head, and F the shank, of a rivet, preferably made ofcopper or cornparatively soft metal. The end of the shank F of the rivetis centrally notched, as indicated at a.

Gis the lining-plate of the button-head, and the outer shell or plate Ais turned over on the lining-plate G, as illustrated in Figs. 2, 10, and11. The plate G has a central rectangular opening Z7, as shown inFig.12, of a size just sufficient to allow the shank F of the rivet topass through it.

The rivet-shank F is passed through the aperture b of the lining-plate Gand inserted in the small open end of the hollow shank B of the button.As seen in Fig. 2, the shank B is flaring and has a large opening 0where it spreads out to form the shoe 0. The sides of the rivet-shank Fare straight and parallel, so that when the rivet-shank F is in position0 in the button-shank B there is a space between the edges of therivet-shank and the inner surfaces of the hollow button-shank, as fullyillustrated in Fig. 2. While the liningplate G and the button-shank Bare held together by suitable means a proper swagingtool is insertedthrough the opening 0 of the shoe 0 and fits the notched end of therivetshank F. A blow of the swagingtool so placed spreads the end of therivet-shank F into contact with the inner surfaces of the button-shankB, as shown in Fig. 10. The result is that the lining-plate G andbuttonshank B are thus riveted together without the use of solder. Uponthe head E of the rivet so fastened in position the inner plate or diskD is placed, and the outer shell or covering-plate A is rolled over theedges of the lining-plate G, as shown in Fig. 2, thus covering the diskD and constituting the head of the button.

The usual shell or covering-plate H is rolled over the edge of the shoe(3, as shown in the several figures.

It is better that the end of the rivet-shank F should be notched, asshown at a; but it may, however, be straight and yet be spread by asuitable tool for the purpose specified.

If desired, the lining-plate G may be formed with the bent lips d atopposite sides of the aperture 12 therein. Such lips, when the parts areassembled, will have their edges abut the outer surfaces of the shank Band will therefore serve to brace or reinforce the connection of thelining-plate Gr with the but ton-shank B. (See Figs. 12, 13, 14, and20.)

In Figs. 15 to 19, inclusive, I show these improved locking means asadapted to a leverbutton. Here the head of the rivet is made oblong inshape, with two opposite edges thereof parallel with each other, and thehead is bent to lie at a right angle with the shank F, and the shank Fis made with a curve 6 and a lip or shoulderf. Thelipfshuts over theupper edge of the shank B, as shown in Figs. 16 and 19. In Figs. 15, 16,and 19 the tilting heads are designated as A and the lining-plates as G,and the plate which rests on the head E of the rivet is a spring-plateand is marked D.

It is a peculiarity of the construction shown that the post or shank Bis rectangular in cross-section, which is a useful novelty, becausewhen, as usual, the collar-button is made of gold-plated stock thebuttonis held in the buttonhole from any rotary or other transversemovement therein, and in consequence the gold is not as soon worn off orthrough as it is when the post or shank is round or oval incross-section, as commonly made.

It is obvious that instead of making the tilting head of the button ovalin shape it may as well be circular.

I claim as a novel and useful invention and desire to secure by LettersPatent- 1. The improved collar-button herein described, consisting ofthe combination ofa shoe having a flaring hollow shank rectangular incross-section, a disk, a lining-plate havinga rectangular aperture, arivet having a head between said disk and lining-plate and also having ashank rectangular in crosssection and made with parallel sides andpassing through said aperture into the hollow button-shank and spreadinto contact with the inner flaring surfaces of said hollow shank, and ashellinclosing said disk, rivethead, and lining-plate and rolled overthe edges of the latter, substantially as set forth.

2. The improved collar-button herein described, consisting of thecombination of a shoe having a flaring hollow shank rectangular incross-section, a disk, a lining-plate having a rectangular aperture, arivet having a head between said disk and lining-plate and also havingashank rectangular in crosssection made with a notched end and parallelsides and passing through said aperture into the hollow button-shank andspread into contact with the inner surfaces of said hollow shank, and ashell inclosing said disk, rivethead and lining-plate and rolled overthe edges of said lining-plate, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES E. POTTER.
